IDT Introduces Family of SPDT Reflective RF Switches Up to 10 GHz

Integrated Device Technology has introduced a new family of high-performance compact SPDT reflective RF switches that operate from 5 MHz to 10 GHz. The F2972 and F2976 offer a mix of low-insertion loss, high isolation, low distortion and high power handling making them ideal for a wide range of markets and applications, including, BTS wireless communications equipment, DOCSIS 3.1 CATV applications, drones, and general purpose consumer products.

The IDT devices are specified for use in either 50 or 75 ohm systems and are available in compact 2 mm x 2 mm packages. Both the F2972 and F2976 have similar RF performance and pin outs, however each device has a unique feature pin. The F2972 offers an enable/disable pin for green, low-power consumption applications. The F2976 has a logic-select feature pin that allows the user to invert the switch control logic, enabling the control of multiple switches with a single control line where each switch needs to be in different states.

The new IDT RF devices feature:

  • Low insertion loss of 0.36 dB and isolation of 42 dB at 2000 MHz
  • Extremely low distortion that allows these devices to be used in a wide range of applications
    • IIP2/IIP3: 120/77 dBm
    • H2/H3: -100/-120 dBc
    • CSO/CTB: >100/>100 dBc
  • Silicon-based semiconductor technology
  • Wide 3.3/5V Vdd and 1.8/3.3V control voltage ranges
  • Wide -40 to 105 C temperature range with an excellent thermal characteristic
